I made a little comparison to the Star Charts:
According to that comparison, the Federation lost 'eastern' parts along the Klingon border and between the Klingons and the Romulans, lost territory in the 'south' and 'north', and gained the 'eastern' part of the Cardassian Union. The Romulan Free State is about 2/3 as large as the former Empire. The Cardassians expanded 'north', and the Ferengi tripled their territory.
